Description: As part of its continuing program of assessment of Southeast Alaska chinook salmon Oncorhynchus tshawytscha stocks, the Division of Sport Fish obtained indices of spawner abundance for all Southeast Alaska and transboundary rivers. The estimated escapement increased from 68,953 fish in 1992 to 101,797 fish in 1993, the highest observed since the start of the program in 1975. The total escapement of chinook salmon in 1993 was 48%, or 32,844 fish, more than in 1992 and exceeded the escapement goal by almost 20,000 fish. The 1993 escapement was three times the 1975-1980 base period average of 32,701 chinook salmon, over twice the 1981-1985 average of 47,187, and 160% of the 1986- 1990 average of 63,606. Escapements exceeded goals in the Stikine (up 73% from 1992), Taku (up 20%) and Situk rivers (down 44%) and in Andrew Creek (up 36%), and were good although below goal in the Alsek River (up 147%). The King Salmon River escapement increased from 117 fish in 1992 to 280 in 1993 (up 139%). Escapements to the Behm Canal systems improved but remained below goals: Unuk (up 22%), Chickamin (up 12%), Blossom (up 102%), and Keta (up 67%) rivers.
